Description

Improvement of water pipe joint structure

This creation relates to the field of water pipe joints. More specifically, this creation improves the structure of water pipe joints to increase the water outlet diameter and reduce the manufacturing process of the joint body.

As shown in Figures 1 and 2, a typical water pipe joint is disclosed, which includes a water inlet 1 and a water outlet 2 that are processed and formed in a solid metal module and are connected to each other and have a round outline, and are formed on the metal The socket portion 4 and at least one connecting portion 5 outside the module. The sleeve portion 4 is formed into a predetermined structure according to a plastic hose (not shown) to be connected to it. The typical structure is tubular and has an outer expanding ring for tightening and preventing the water pipe from slipping out. The connecting portion 5 is formed into a predetermined structure according to other joints or water source joints to be connected thereto, and a typical structure is an external thread.

The plastic hose is sleeved outside the sleeve portion 4. When the two are sleeved, a rotary thrust is required to be applied to the water pipe joint. The size of the water pipe joint is not sufficient for the operator to hold and apply the rotary thrust, so the internal reprocessing A polygonal tool hole 3 is formed so that the polygonal working end of the tool rod uses the tool hole 3 to drive the water pipe joint to rotate and apply propulsive force.

One of the shortcomings of the above-mentioned typical water pipe joint is that the circular outlet hole 2 needs to retain a large wall thickness to be provided to the sleeve portion 4 during processing, so the diameter of the outlet hole 2 is limited, the amount of water is small, and it is easy to cause water flow through The pressure of the water outlet 2 increases, and the water pressure impinges on the water pipe is prone to the problem of the plastic hose loosening from the socket. The second shortcoming is that the water inlet 1, the water outlet 2 and the tool hole 3 are processed and formed in stages. The process is more cumbersome.

In order to solve the above problems, the author improved the structure of the water pipe joint, increased the water outlet diameter, corrected the problem that the diameter ratio of the water inlet and the water outlet hole was too large, and reduced the joint body processing steps.

Technical features of this creation: An improved water pipe joint structure, including: a water inlet hole and a water outlet hole formed inside a metal module and communicating with each other, and a set of connecting parts formed outside the metal module for connecting a plastic water pipe and a At least one connecting part connected to other joints or water source joints; the cross-sectional profile of the water outlet is polygonal.

Original creation effect: In this creation, the outlet of the water pipe joint is changed to a polygon, so that it has the dual function of the outlet and the tool hole. Compared with the typical water pipe joint described in the previous technology, this creation eliminates the typical water pipe The tool hole of the joint reduces the processing procedure of remaking the tool hole of the joint body.

The water outlet of this creation is polygonal, and its water output is larger than the water output of the circular water outlet of the typical water pipe joint of the same specification. The water pressure impact through the water outlet is relatively reduced, so that the plastic hose is connected from the sleeve due to the water pressure impact. The problem of loose parts is reduced.

In order to facilitate the explanation of the central idea expressed in the column of the above-mentioned new content, the specific embodiment is hereby expressed. In the embodiments, various objects are drawn according to the proportion, size, deformation or displacement suitable for description, rather than drawn according to the proportion of actual elements, which will be described first. In the following description, the same and symmetrically arranged elements are denoted by the same number.

As shown in Figs. 3 and 4, the original water pipe joint includes a water inlet hole 10 and a water outlet hole 11 formed inside a metal module and communicating with each other, and a set of connecting portion 12 and at least one connecting portion formed outside the metal module 13; The cross-sectional profile of the water outlet 11 is a polygon, including but not limited to a quadrilateral, hexagon, octagon, or asymmetric shape. The sleeve portion 12 is formed into a predetermined structure according to the plastic hose to be connected to it, and is typically a tubular body with an outer expanding ring for pressing and preventing the water pipe from slipping out; the connecting portion 13 is formed according to The other joint or water source joint to be connected to it is made into a predetermined structure, and the typical structure is an external thread.

The water hole 11 can be drilled in the process of forming a solid metal module into a water pipe joint, or the water inlet hole 11, the sleeve portion 12, and the The connecting portion 13 uses the polygonal hole as the water outlet 11.

As shown in Figs. 5 and 6, the plastic hose 20 is sleeved outside the sleeve portion 12. When the two are sleeved together, a hand tool 21 with a polygonal working portion 211 is inserted through the water outlet 10, and the tool works at a polygonal angle The portion 211 is combined with the water outlet 11, and a rotary thrust is applied to the water pipe joint by the hand tool 21, so that the sleeve portion 12 is smoothly sleeved with the plastic hose 20.

As can be seen from the above description, this creation changes the outlet 11 to a polygonal shape to make it both Compared with the typical water pipe joint described in the prior art, the dual function of the water outlet hole and the tool hole eliminates the tool hole of the typical water pipe joint, and reduces the processing steps of the joint body to remake the tool hole. Furthermore, the water outlet 11 of this creation is polygonal, and the size of the polygon is set by using the radius of a circular water outlet of a typical water pipe joint of the same specification as the inscribed circle. Therefore, the polygonal outlet 11 of this creation The water output is greater than the water output of the circular water outlet of the typical water pipe joint of the same specification. The water pressure impact through the water outlet 11 is relatively reduced, so that the problem of the plastic hose 20 loosening from the socket due to the water pressure impact is reduced. .
